Abstract
More than half of the world population lives in Asia and hypertension (HTN) is the most prevalent risk factor found in Asia. There are numerous articles published about HTN in Eastern Mediterranean Region (EMRO) and artificial intelligence (AI) methods can analyze articles and extract top trends in each country. Present analysis uses Latent Dirichlet allocation (LDA) as an algorithm of topic modeling (TM) in text mining, to obtain subjective topic-word distribution from the 2790 studies over the EMRO. The period of checked studied is last 12 years and results of LDA analyses show that HTN researches published in EMRO discuss on changes in BP and the factors affecting it. Among the countries in the region, most of these articles are related to I.R Iran and Egypt, which have an increasing trend from 2017 to 2018 and reached the highest level in 2021. Meanwhile, Iraq and Lebanon have been conducting research since 2010. The EMRO word cloud illustrates 'BMI', 'mortality', 'age', and 'meal', which represent important indicators, dangerous outcomes of high BP, and gender of HTN patients in EMRO, respectively.

Blood pressure during long-term cilostazol-based dual antiplatelet therapy after stroke: a post hoc analysis of the CSPS.com trial. Hypertens Res 2024; 47:2238-2249. [PMID: 38977876 PMCID: PMC11374707 DOI: 10.1038/s41440-024-01742-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 05/09/2024] [Accepted: 05/13/2024] [Indexed: 07/10/2024]
Abstract
We determined the associations of follow-up blood pressure (BP) after stroke as a time-dependent covariate with the risk of subsequent ischemic stroke, as well as those of BP levels with the difference in the impact of long-term clopidogrel or aspirin monotherapy versus additional cilostazol medication on secondary stroke prevention. In a sub-analysis of a randomized controlled trial (CSPS.com), patients between 8 and 180 days after stroke onset were randomly assigned to receive aspirin or clopidogrel alone, or a combination of cilostazol with aspirin or clopidogrel. The percent changes, differences, and raw values of follow-up BP were examined. The primary efficacy outcome was the first recurrence of ischemic stroke. In a total of 1657 patients (69.5 ± 9.3 years, female 29.1%) with median 1.5-year follow-up, ischemic stroke recurred in 74 patients. The adjusted hazard ratio for ischemic stroke of a 10% systolic BP (SBP) increase from baseline was 1.19 (95% CI 1.03-1.36), that of a 10 mmHg SBP increase was 1.14 (1.03-1.28), and that of SBP as the raw value with the baseline SBP as a fixed (time-independent) covariate was 1.14 (1.00-1.31). Such significant associations were not observed in diastolic BP-derived variables. The estimated adjusted hazard ratio curves for the outcome showed the benefit of dual therapy over a wide SBP range between ≈120 and ≈165 mmHg uniformly. Lower long-term SBP levels after ischemic stroke were associated with a lower risk of subsequent ischemic events. The efficacy of dual antiplatelet therapy including cilostazol for secondary stroke prevention was evident over a wide SBP range.
